“5G is human-focused”


From hologram-based communications to remote-controlled surgical procedures – the 5G wireless standard has made many high-tech applications a reality. A serious project now being launched at the Technical University of Munich (TUM) aims to determine the key technical criteria for the new standard. During this interview, project leader Prof. Wolfgang Kellerer explains how 5G has become the foremost intelligent wireless network, when Germany could combat a number one role and why, within the world of research, new speed records are smaller than ensuring 99.999999999% reliability.

The 5G Future Lab Bavaria at TUM is considered Germany’s largest university scientific research for the sixth wireless communications generation. The project is a component of the Bavarian 5G initiative, that the Bavarian Ministry of Economic Affairs will provide a minimum of 5 million euros in funding. Over subsequent three years, 12 research professorships has developed fundamental mechanisms for 5G and draw up a roadmap for its standardization and rollout. Project leader Prof. Wolfgang Kellerer is additionally one among the 2 spokesmen for the Thinknet 5G platform.

Is 5G already obsolete?

5G has a great future ahead But there’ll be differences within the applications. 5G plays an important role for Industry 4.0, facilitating a replacement dimension of machine-to-machine communication. In 5G, the main target is on humans and their surroundings.

But you don’t mean humans and their phones?

Not primarily. It’s more a few wide selection of technologies integrated into our everyday lives that we interact with almost stupidly about it. It is  because of excellent wireless communications and sensor technology. It’d be robot assistants within the household, high-resolution 3D maps for self-driving vehicles or holograms enabling us to see people we are lecture . With 5G, remote-control surgery and other applications requiring precise positioning of kit has  become a reality.

What bandwidths will 6G be capable of?

We believe that the upper frequencies used for 5G  allow a knowledge transfer rate of 1 terabyte per second. However, the speed records aren’t the most priority in our research program. We would like to get the inspiration to realize the very best fail-safe standards, shortest latency times and maximum energy efficiency. We also want to make new processes to make sure data security even by use of quantum computers .

At first glance, those appear as if secondary criteria.

On the contrary: those are the essential points for the high-tech applications that represent the promise of 6G. Consider telesurgery, for instance . When lives are at stake, we can’t accept 99.9% reliability. For the 6G network, we are aiming for 99.999999999% fail-safe reliability.

Another example is that the scenario where humans and robots work together. If these assistants are utilized in lifestyle or medical care settings, they’re going to be very on the brink of people. For that reason, when controlling them, latency – in other words the delay when processing wireless signals – has got to be on the brink of zero. After all, only one false reaction by a robot could cause personal injury or property damage during a blink of an eye . For 6G we would like to realize latencies well under one millisecond.

We want these specifications to be guaranteed for end-to-end communications across multiple network. Because communications aren’t generally limited to the network of 1 provider. Which may sound trivial, but it involves enormous challenges. Finally, we would like the whole network to be intelligent.

What does intelligence mean for a wireless network?

With AI , the network can conduct its own calculations to continuously optimize itself. It should be flexible and adaptable to the purpose where it can deliver the specified performance when and where it’s necessary.

6G are going to be the only wireless communication generation. Through it the network works along side countless sensors positioned within the networked devices like robots and self-driving vehicles. At an equivalent time, the network can now become a sensor itself, with the wireless signals getting used to get certain information like the presence of an object between the transmitter and receiver. The AI technology can then use of these data to make an image of the user’s surroundings. Therefore the communication requirements and adapt the network accordingly.

The big challenge is to develop network architectures that are ready to make optimal use of the characteristics of various sensors and also are trainable. Consequently, a core element of our research is digital twins. Industry already uses these virtual images of objects. For instance , a computer creates an in depth digital replica of a producing plant. This makes it possible to explore and optimize the workings of the plant. We would like to make digital twins of the network and its components to optimize them with machine learning methods.

When will 6G be able to use?

Experience shows that it takes around 10 years to develop a replacement wireless generation. To be ready for an enormous rollout within the early 2030s, those folks doing basic research want to figure with the opposite key actors right from the beginning to get the groundwork for fulfillment . We would like to find out about the expectations of the business and society at large. This networking will now happen on the Thinknet 6G platform.

In the context of the wireless generation cycle, we are literally starting before usual with the event of subsequent generation.

Does this mean that Germany features a chance to play a number one role in 6G?

Yes. we would like to make the conditions for companies to be among the leaders right from the beginning . We would like to ascertain start-ups emerging and to supply leading experts through our degree programs.

And with vital infrastructure of this type , sovereignty is additionally a top priority. When network components fail, we should be during a position to exchange each and each one among them ourselves.
